Overview
Boneset (Eupatorium perfoliatum) is an upright perennial herb in the aster family, native to eastern North American wetlands. It is easily recognized by its perfoliate leaves, paired leaves fused around the stem so the stem appears to pass through a single leaf.
In late summer it bears flat-topped clusters of small, dull-white flowers that draw a wide range of bees, butterflies, and beneficial insects.
Its upright, colony-forming habit and reliable late-season bloom make it a favorite for native plantings and moist borders.
